SpaceX Scrubs Tuesday Launch
The private spaceflight company SpaceX has called off tonight's planned launch of the communications satellite AsiaSat 6, according to media reports. There is no word yet as to the cause of the scrub or when the next attempt will be.
SpaceX had planned to launch the telecommunications satellite AsiaSat 6 at 12:50 a.m. ET (0450 GMT) Wednesday (Aug. 27) from Florida's Cape Canaveral Air Force Station. Check back in with Space.com for more updates.
A SpaceX-built Falcon 9 rocket will launch AsiaSat 6, marking the company's second launch this month for customer Asia Satellite Telecommunications Company Limited (AsiaSat). On Aug. 5, SpaceX launched AsiaSat 8 into orbit.
For AsiaSat 6, SpaceX will launch the satlelite into a geosynchronous transfer orbit that ranges between 185 kilometers and 35,786 kilometers above Earth. The satellite is expected to be deployed from the Falcon 9 rocket's upper stage about 32 minutes after liftoff, according to a SpaceX mission press kit. SpaceX has backup launch windows on Thursday and Friday, if needed.
The AsiaSat 6 launch will mark the fifth launch of 2014. The mission was originally slated to launch in May, and then on Aug. 26. It was delayed one more day while SpaceX analyzed a recent failure of a three-engine Falcon 9 Reusable rocket prototype during an Aug. 22 test launch in Texas. The delay was only a safety measure, as the Falcon 9 rocket launching AsiaSat 6 has a different nine-engine configuration, SpaceX officials said in an update.
HD Views from the International Space Station
NASA is now live-streaming views of Earth from space captured by four commercial high-definition video cameras installed on the exterior of the International Space Station. The project, known as the High Definition Earth Viewing (HDEV) experiment, aims to test how cameras perform in the space environment.
